I have a 22 equinox rs and am about to install a hitch receiver and had a question about the trailer wiring. I’ve never towed anything before and it’s kind of overwhelming. I’m not sure if I have the factory tow package or not and no one from the dealership seems to know either. There was no factory installed hitch but the factory wiring harness is there. I’ve been looking at the curt 56429 but it says it requires factory tow package. I have the connector there and it looks plug and play but I’m not sure. Does anyone know what wiring harness part number I need? Thanks in advance for any help.
